Welcome to NT U2P!

My bout with ON was mild compared to what you are experiencing. I know that others on here have experienced ON such as you have described. I am sure they will be along to answer your questions.

I know that steroids for ON are very helpful especially if started within the first 72 hours of an attack. I could be wrong, but I believe that ON eventually resolves. For some, the symptoms resolve completely and for others they are left with some symptoms. Again, I could be wrong. I have been fortunate that my episodes of ON have resolved with no lingering symptoms.

Hang in there and please let us know how you are doing.
